Soil & Land Strata: The land strata of the project site varied extensively with presence of small dunes in a sandy terrain. Naturally, the project team faced immense difficultly in moving the construction equipment and machineries. The project team encountered rocks at depth of 0.5 m, 1.5 mm and complete sand due to which the pilling work was done at 3 different depths in Zone A, Zone B & Zone C.
Mitigation: Temporary murram road was built to access the site for construction and moving of machineries.
Weather: Extreme weather conditions at the project site posed a problem. The summer temperature was as high as 50°C; from April to July, cyclonic storm ensued with prevalence of strong wind between 11 am to 4 pm and work came to a halt. Similarly, the temperature during winter was as low as 5°C (night).
Mitigation: Controlled working hours along with a dynamic work schedule allowed us to deliver the project on time. Continuous hydration of the workers ensured better productivity.
Local Manpower: The project’s major problem lied with local unskilled manpower.
Mitigation: We had to engage and train local workers for temporary works and hire tractors, trolleys and other small machineries locally to aid the process.
Construction Power and Water: This project had a multitude of problems. Firstly, there was an absence of a continuous power source. But arranging for it with immediacy was quite difficult considering the remoteness of the area. Also, quality of the available bore well water was not suitable for going ahead with the construction work in an uninterrupted way.
Mitigation: We procured power from RRECL for construction site and used Diesel Generator sets to get uninterrupted power. For civil works, we had to arrange for canal water from nearby areas.
Murram Sourcing: Sourcing of murram was a challenge in the area. The process of getting approval from the mining department was tough and required extensive compliances and certificates from our side.
Mitigation: We provided all the backings and fulfilled the compliances for getting the permission from the mining department for sourcing the murram.
Total 4,40,000 solar PV modules (approx.) were installed in the 130MW plant.
Total 7500MT of steel were used for the mounting of the module structure.
Each 65MW block has a unique switchyard which steps up the plant voltage from 33kV level to 132KV level with the help of 63MVA grid transformer.
Expected Annual Energy Yield 212.44 million unit. The plant is also expected to reduce CO2 emissions to the tune of 203942.4 metric tonnes annually.
